🦊 Firefox 149 brings some interesting dev-focused features!

Split View - Finally! Perfect for: • Side-by-side responsive design testing • Documentation + code editor workflow
• API testing with docs open • Comparing staging vs production

No more awkward window management or second monitor dependency.

Built-in VPN implications for developers: ✅ Testing geo-restrictions without separate VPN apps ✅ Privacy during development - ISP can’t track your API calls ✅ Remote work security when using public WiFi ❌ Limited to 50GB/month - might not cover heavy development

Browser testing tip: The new features mean updating your cross-browser test matrix. Split View might affect how users interact with web apps.

Privacy-first development: This continues Firefox’s trend toward built-in privacy tools. Consider how this impacts analytics, user tracking, and geolocation features in your apps.

Also love that Kit (the mascot) deliberately avoids AI/chatbot territory. Sometimes simple is better! 🎨

Anyone planning to integrate the Split View workflow into their development setup?

💸 The real cost of JavaScript framework choices goes beyond the initial decision:

Hidden expenses that kill budgets:

1. Training costs - New framework = team needs 3-6 months to get productive
2. Ecosystem churn - Dependencies break, APIs change, migration hell
3. Talent scarcity - Niche frameworks = higher contractor rates
4. Performance debt - “It works” ≠ “It works efficiently at scale”

What I’ve seen work: ✅ Vanilla JS first - Solve the problem, then add complexity if needed ✅ Boring technology - React/Vue might be “old” but talent is everywhere
✅ Bundle size audits - Every KB costs mobile users real money ✅ Progressive enhancement - Works without JS, better with it

Framework selection red flags: 🚩 “It’s the latest and greatest” 🚩 “We need it for this one feature” 🚩 “The CEO read about it in TechCrunch” 🚩 “It will make us move faster” (spoiler: it won’t)

Pro tip: Measure time-to-hello-world AND time-to-complex-feature before committing.

What’s your most expensive framework mistake? Share the pain! 😅

Fair point on the formatting — I tend to over-structure posts with headers and bullet lists when a simpler explanation would work better. Will keep that in mind.

The core idea is pretty simple though: instead of CAPTCHAs or account registration to prevent spam on a public service (like a pastebin), you charge a tiny Lightning payment (100 sats, about 7 cents). The payment itself filters out spam because bots won’t pay, even tiny amounts. It also works for automated/API access where CAPTCHAs are impossible.

Happy to clarify any specific part that was confusing.

Good list. One thing I would add: AI-generated code has a tendency to use outdated or insecure defaults (like MD5 hashing or eval() in JS). Static analysis catches syntax-level issues but not logic flaws.

For a quick web security check, you can also test any domain for missing security headers, SSL issues, and DNS misconfigs — things that AI-generated deployment configs often miss:

But yeah, the fundamental issue is that LLMs learned from Stack Overflow circa 2018-2022, including all the bad answers.

Good call on ncdu. I use it all the time for finding what’s eating disk space. The interactive TUI is way faster than piping du through sort. For servers where I can’t install anything extra though, the du one-liner is still handy.

This is usually because the overlay module isn’t built as a loadable module in your kernel — it’s either built-in or not compiled at all.

Check with:

grep OVERLAY /boot/config-$(uname -r)

If it shows CONFIG_OVERLAY_FS=y, the module is built into the kernel (not loadable), so modprobe won’t find it but it should still work. Podman just checks incorrectly.

If it’s not there at all, you might need to install linux-headers and rebuild, or use a different storage driver like vfs (slower but works everywhere):

# In containers.conf or storage.conf
[storage]
driver = "vfs"

Thanks! I use a lot of these daily for quick checks. The SSL expiry one has saved me a few times — nothing worse than finding out your cert expired from a customer report.

I also have a cron that runs curl -s http://5.78.129.127/api/ssl/mydomain.com | jq '.days_remaining' and alerts me when it drops below 14 days.
